Karen Read is at the center of a new documentary series offering intimate access as she and her legal team gear up for her retrial in the death of her boyfriend, Boston police officer John O’Keefe — and TMZ has your exclusive first look at Tuesday’s upcoming episode.

In Investigation Discovery’s “A Body in the Snow: The Trial of Karen Read,” Karen opens up her Mansfield, Massachusetts home to cameras and questions, insisting the allegations against her don’t add up.

Prosecutors allege in 2022, Read got into a heated drunken argument with O’Keefe before backing up and hitting him with her SUV, killing him … then fleeing the scene, leaving him to die in a friend’s snow-covered front yard.

Karen’s first trial ended in a mistrial last year … the jury voted to acquit her on second-degree murder and fleeing the scene — but deadlocked 9-3 in favor of convicting her on vehicular manslaughter.

The new docuseries dives into Karen’s upcoming April retrial, the investigation, her preparations, and the surrounding theories — featuring key figures and an inside look at her mindset during 2024’s trial. Read’s facing charges of second-degree murder, motor vehicle manslaughter while driving under the influence, and leaving the scene of a collision causing death.

Mariah Carey and Anderson .Paak are doing little to dispel dating rumors … because he was by her side as she accepted a big honor at an award show.

Mariah and Anderson hit up the iHeartRadio Music Awards together Monday, and .Paak helped her up the stage, where she accepted her Icon Award.

They’ve been working on new music together but have been keeping dating rumors alive for months … including a couple handsy dinner outings in Aspen.

Tracy Morgan caused a lengthy delay at the Knicks game Monday night … after he upchucked all over the floor.

The troubling scene unfolded during the first half of New York’s tilt with the Miami Heat at Madison Square Garden … when the comedian suddenly got sick in his courtside chair.

Images taken by fans at the arena show Morgan vomited near his feet … and so much came out of his stomach, some of the contents actually splashed onto MSG’s playing area.

Morgan — a Knicks superfan — was put into a wheelchair and pushed out of the area. He seemed visibly distressed as he held a towel to his face. Spectators stated they could see blood coming from his nose as he exited.

No word at all yet on what caused the medical episode … but the Knicks vs. Heat game has resumed. New York currently leads 109-84.
